Practice of Four Section Rolling Process Transformation for Φ12mm Threaded Steel
In the production practice of the three section rolling process of Φ12mm threaded steel for the first bar production line of Yangchun New Iron and Steel Co.,Ltd.,the production efficiency is low,with a daily output of only about 2 700 tons,far lower than the production capacity of the No.1 steelmaking casting machine.This has led to a low hot delivery and charging rate,significant energy waste,and seriously hindered the company's capacity improvement.In view of this,this article introduces the successful improvement of the production process of Φ12mm threaded steel from three cutting to four cutting by utilizing old existing equipment on a rolling line.After the transformation,not only has the production efficiency been improved,but also the cutting line difference is small and the product accuracy is stable and controlled,which has strong reference significance.
